To all whom it may concern.-

Be it known that I, ARTHUR NEAL FUNK, a citizen of the United States, and a resident of Fort Worth, county of Tarrant, and the State of Texas, have invented new and useful Improvements in Advertising Attachments for Scales, of which the following is a specification.

My invention is an improvement in advertising attachments for scales, and has for its object to provide an attachment of the character specified, wherein a series of display members are provided, mounted to be moved into different positions, to bring different matter into display position, and controlled to movement by the stepping onto til the weighing platform of the one to be weighed.

In the drawings:

Figure 1 is a vertical section;

Fig. 2 is a vertical section at right angles to Fig. 1;

Fig. 3 is a detail of the locking device, with parts in section;

Fig. 4c is a perspective view of one of the display members.

The present invention is especially adapted for use with weighing scalesof the automatic type, and the invention is shown in connection with a scale of this character indicated at 1. The hollow standard 2 that extends up from one end of the platform, and communicates with the chamber 3 in the platform carries a casing 4 at its top.

This casing has a series of horizontally extending slots or openings 5 in the face adjacent to the platform, and behind these openings within the casing are arranged the display members. In the present instance, each of these members is a roller 6 of triangular cross section, having three faces, upon which advertising matter of any desired character may be placed.

Each roller has axial journal pins 7 at its ends, and these pins are journalcd in the end walls of the casing, so that the rollers may be rotated to bring either face to the front, and the slots 5 are of a size to display almost the full area of a face.

The rollers are constrained to rotate together and in unison by means of a sprocket chain 8, which engages sprocket wheels 9 on the rollers at one end. Each roller has a sprocket wheel, and there are in the present instance four rollers.

A locking means is provided for holding the rollers with the display faces squarely before the openings; the said means being spring controlled, and releasable but preventlng accidental displacement of the rollers. It willbe understood that the rollers are so connected by the chain that the display faces of the series of rollers will be always in the same plane.

This locking means comprises a cam wheel or disk 10, secured to one of the rollers, in the present instance, the second from the bottom, and this wheel has depressions 11 in its periphery, corresponding in number and relative position to the number and relative position of the display faces.

1 locking wheel or roller 12 engages the periphery of the cam disk, the said'roller bemg journaled between arms 18 on the end of a rod 14, which is mounted, to slide in a casing or cylinder 15 secured to the rear wall of the casing 4:. 7

The rod has a head 16 at its inner end, fitting the casing, and a coil spring 17 is arranged between the head and the bottom of the casing, and acts normally to force the roller toward the cam disk. When the cam wheel is turned, the raised portions thereof will move the roller 12 away from the disk,

.face is flush with the upper face of the platform of the scale.

A lever 20 is pivoted within the chamber 3 intermediate the ends of the lever and to the top of the chamber, as indicated at 21,

and the forward end of this lever has an upwardly extending angular portion 22, which passes through to an opening in the top of the platform 4 and engages the under face of the auxiliary platform near its free end.

The rear end of the lever 20 is connected to the lower end of the lower section 23 of a rod consisting of the portion 23 and a portion 23. This rod 23-23 is mounted to slidevertically in the standard 2 and the portion 23 of the rod has a head 24 at its upper end.

The head 24 has a slot 25 extending transversely of the head, and a pin 26 on one end of a lever 27 engages within the slot. The lever is pivoted at 28 intermediate its ends,

and the end remote from the pin is connected by a link 29 with a pawl or pusher 30, which cooperates with a ratchet chain 31*. This'chain is supported-by sprocket wheels 32 and 33, on the lowermost roller 6, and on the wall of the casing 41, and it will be obvious that when the rod 23 is moved upward by the downward movement of the'auxiliary platform the pawl will be pushed downward and the rollers will be turned.

The arrangement is such that the swinging of the auxiliary. platform. into the rabbet of the platform 4; under the weight of the userv will advance the chain 31 far enough to move .each roller 6 a suilicient distance to bring another display face into display position.

The rod 23 is normally pulled downward by coil springs 30 which are arranged be tween the rod and the opposite side walls of the hollow standard. Should this rod 23 be connected directly to the lever 20 at all times, the fine adjustment of thescale might be disturbed, and means is provided for releasing the connection when the change of the rollers 6 has been made.

The sections 23 23 of the rod are normally out of alinement and so held .by a cross pin 31 in the standard which is engaged by a cam block tion 23. A coil spring 33 normally acts to draw the said lower section toward the pin.

When the section 23 of the rod is moved upward by the swinging of the lever 20, the engagement between the cam and thepin will cause the section tomove rearwardly at its upper end and away from the adjacent end of the section 23. The ends are' always out of alinement, and the section 23 en ages an. extension 34 on the section 23.

The operation of the device is as follows:

hen one steps upon the auxiliary platform, it is depressed until it rests upon the weighing platform. The lever 20 is rocked, the section 23 of the rod 23-23, is moved upward, and the end-of it engages the nose or extension 34 of the section 23.

his section is also moved upward and the chain 31 is moved to cause the lowermost display roller'to turn far enough to display another face at the adjacent opening 5. Since the display rollers are constrained to turn together, each brings. to View a new face, and all are before the one being weighed.

The cross rod 31 acting on the cam 32 is gradually moving the section 23" rearwardly, and at the'moment when the auxiliary platform is fully depressed and the display rollers are in display position, the section 23 is moved out of engagement with the section 23, that is, the connection between the auxiliaryplatform and the display rollers is broken.
